I've used that one in Calgary and the owners are super helpful the times I've been there. First time I figure I wanted to learn how to mount & balance tires myself. After watching a bunch of Youtube and studying the theory, I thought I had the concept down in my head really well...but when it came down to using the machine I sure as heck struggled. The nice lady there showed me how to do my first tire. With these being larger heavy duty truck tires, I struggled ALOT with the rest of the tires and definitely felt bad with how much help I asked for. In the end it took me over an hour to do all four tires and $50. The tire machine definitely seemed to be popular there, but to be honest it's not really worth it trying to do tires yourself to save a few $$.
In the end, it's a pretty good deal for the customer trying to access specialty tools like the hydraulic press and tire machine especially considering how helpful the owners were. But I really don't see how they make money because when you have an average Joe customer go in, they can easily hurt themselves or spend a whole bunch of time there and/or require alot of support.
